I WESPECIPICATION forming part of Letters Patent No. 300,164, dated June 10, 1884-.

Application filed May 3,1883. (No model.) Patented in England May 6, No.4,0'24.

To aZZ whom it may concern;

Be it known that 1, WILLIAM H. THOMP- SON, a citizen of New Brunswick, in the Dominion of Canada, and a resident of the city of New York, in the county and State of New York, United States of America, have invented a certain new and useful Improvement in Apparatus for Extinguishing Fires upon Steam or other Ships or Structures of any Kind, of which the following is a specification.

My inventionrelatcs to a fire-extinguisher; and it consists in the parts which will be hereinafter described, and pointed out in the claims.

The device is particularly adapted for use on steam and sailing vessels. It may, however,

' be used in buildings, 85c.

In carrying my invention into effect I insert a series of. vertical pipes of different lengths into the several compartments below the main deck. The upper ends of these pipes are substantially flush with the deck, and their necks enter in and are secured toa quadrantal plate fixed to the deck. The upper ends of these pipes are suitably connected by branch pipes with a main steam-pipe. Said branch pipes are provided with suitable cocks or valves, whereby the flow of the extinguishing material (steam or steam and carbonic-acid gas) may be regulated. In the use of steam and carbonic-acid gas I interpose a gas-generating chamber between the vertical compartment-pipes and the steam-pipes-that is to say, I connect said chamber with the branch pipes at a convenient point between the steampipe and quadrant.

In the accompanying drawings, Figure 1 is a transverse section of a ship provided with my improvement. Fig. 2 is a plan View of the main supply-pipe, provided with a threethrow pipe having a swivel-connection'in said supply-pipe, also showing a gas-generator fixed to the shifting pipe and a quadrantal plate in which the necks of the compartmentpipes are secured. Fig. 3 is a plan view of the main supply and shifting pipes and the quadrantal plate. The dotted lines inthis view indicate the positions of the shifting- F represents three openings in said plate, in which the necks of compartment-pipes G H I are secured. The pipe G leads to the first compartment, H, to the next below, and I extends to the bottom one. J represents a shifting pipe having a loose end, J, and a swivel end, J The loose end J is adapted to engage the necks of any one of the pipes G H I in the quadrantal plate E, whereby the extinguishing material may be conveyed from the main supply-pipe Lto any one of the compartments B G D. I

K is a plug having an opening therein, and provided with a socket in its upper side for the reception of the end J of the shifting pipe J. The end J 2 turns in the socket of the plug. The lowerend of this plug is engaged to the main supply L.

M is a carbonic-acid-gas generator fixed to the pipe J, and adapted to move therewith. This generator is shown in Figs. 1, 2, and 4, and is used when desired to combine steam with carbonic-acid gas for extinguishing fires.

for the transmission of steam only from the sup- E is a quadrantal plate fixed to the deck A.

ply pipe L to the compartment-pipe through the medium of the branch pipe or pipes. The gas-generator is omitted in Fig. 3. The pipe J, as shown in Figs. 1, 2, and 4, is connected with the generator M, whereby steam alone may be used, or the steam combined with carbonic-acid gas. The pipe J has a swivel-connection with the supply or feed pipe L either directly or through the interposed valve K. The pipe J in its swivel function may be used with or without the generator M.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a fire-extinguishing apparatus, a series of vertical pipes of different lengths, terminating in separate compartments, the upper 50 pipe when thrown to either the right or left. ends whereof are flush and arranged in the ments, in combination with a main supply- 1 pipe, having one end of a branch pipe swiveled thereto, and a cock, K, the loose end of said branch pipe being adapted to engage any one of the openings in the quadrantal plate, substantially as described, and for the purposes set forth.

3. In a fire-extinguishing apparatus, a series of vertical pipes of different lengths, terminating in separate lower compartments, the upper ends whereof are flush, in combination with a main supply-pipe having a swivel feedpipe connected therewith, said feed-pipe be ing provided with a gas-generator, substantially as described, and for the purposes set forth.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 16th day of April, 1883. 0
